Adding RSpec tags based on CODEOWNERS

codeowner_tagging.rb

# Allow spec to be run by the owner specified in the CODEOWNERS file.  The @joinswoop/ prefix is assumed
#
# eg. bin/rspec --tag codeowner:squad-network-be
#
RSpec.configure do |config|
  # NOTE: Attempted to only apply these if a codeowner tag was supplied in the configuration
  # However, it appears that this gets evaluated before the command line options are parsed and
  # could not find a way to optimize this.
  File.readlines('CODEOWNERS').each do |line|
    next unless line.start_with?('/spec/')

    path, owner = line.split
    next unless path.present? && owner.present?

    config.define_derived_metadata(file_path: /#{path}/) do |metadata|
      metadata[:codeowner] = owner.delete_prefix('@joinswoop/')
    end
  end
